The graphic controller 7a expands and stores the map screen data calculated by the main controller 1 from the map data and the recommended route data calculated by the main controller 1 in the video RAM 7b, and displays the map screen data in the RAM 7b on the display device 7c.

The display device 7c also serves as a touch panel as an input device. The voice output device 8 outputs a voice guide message as appropriate according to a command from the main controller 1. The microphone 9 inputs an audio signal to the main controller 1.

In the on-vehicle navigation apparatus having the above-mentioned structure, the battery-backed point information storage area stores bit information, bit number data, and the like for storing the latitude and longitude, point marks, etc. of the point information 1, point information 2,. 1, a bitmap area for storing handwritten graphic information of bitmap data 1... And an audio area for storing audio information of audio data 1, audio data 2.

In the area of the point information 1, the point information 2,..., A pointer to each address of the bitmap data 1, the bitmap data 1,.

In order to store handwritten graphic information in the bitmap area, a point number is designated by the input device 6, and then a point edit menu screen shown in FIG. When selected, the screen of the touch panel shown in FIG.

Therefore, as shown in FIG. 4, an arbitrary figure or character is written, and the address of the bitmap data is stored in the pointer at the designated point number by pressing the decision button, and the address stored in the pointer is stored. Is written in the bit map area.

When the resolution of the touch panel is low, a plurality of screens can be connected and stored. In this case, the input device 6 is operated to operate the address stored in the address pointer as shown in FIG.
A plurality of areas 3 and 4) are displayed, and handwritten characters or figures are input in each area.

These characters or figures are connected and displayed on a display device. The input handwritten character or graphic is reduced to an appropriate size and displayed as a point icon superimposed on the map screen as shown in FIG.

When a voice signal is stored in the voice area, a point number is designated by the input device 6, and then a point edit menu screen shown in FIG. 3 is displayed on the display device 7 and "voice" is selected by the cursor. The signal input from the microphone 9 is written to the address of the voice area of the pointer of the designated point number.

The character or graphic data stored in this way is displayed as an icon together with a point number when setting a destination or the like in a list, and can be used for identification of the destination.

Further, during operation, the distance from the position of the vehicle to the registration point is calculated periodically from the latitude and longitude of the registration point near the vehicle and the latitude and longitude of the vehicle. As shown in FIG. 7, the bitmap information is displayed in a pop-up manner, and voice information is played to notify the driver that the registered point is approaching.

The embodiment is configured as described above.
The invention is not limited to this, for example, a character recognition device is provided,
Handwritten input can be recognized as a character, and the recognized character code can be stored as point information. In this case, the bitmap memory area can be saved.

[0030]

According to the navigation apparatus of the present invention, when inputting or changing a point name, the trouble of searching for characters on the screen can be saved.

Further, figures, symbols, etc. other than characters can be input, and the degree of freedom of information is increased. Further, since the voice information is played, the number of times of viewing the monitor during driving is reduced.
